Incomplete-Fusion Reactions in theN14+Tb

Observation of incomplete fusion at low angular momenta

“…However, on the basis of the above prescription, ICF reactions could not be explained at lower projectile energies, where the maximum angular momentum values ( max ) are less than the critical angular momentum ( critical ). The γ-multiplicity measurements by Wilczynski et al [9], Inamura et al [10], Gerschel et al [11], and Trautmann et al [12] also indicate that such breakup fusion, in general, involves ≥ critical . However, studies [13] on spherical targets showed involvement of -values in ICF lower than critical as well, giving rise to conflicting reports on the a e-mail: dpsingh19@gmail.com dependence of ICF on the angular momentum.…”

“…However, studies [13] on spherical targets showed involvement of -values in ICF lower than critical as well, giving rise to conflicting reports on the a e-mail: dpsingh19@gmail.com dependence of ICF on the angular momentum. Further, it may be pointed out that the available theoretical models [9,[14][15][16][17] satisfactorily predict the magnitude of ICF contribution, to some extent, in some cases at energies ≈10 MeV/nucleon, but none of these models is able to successfully explain such data at low energies. In view of the above, a clear picture of the mechanism of ICF has yet to emerge, particularly at energies ≈3-5 MeV/nucleon.…”

“…Interestingly, α-emitting channels at energies ≈3-6 MeV/nucleon are found to show enhancement of cross-sections over the statistical model predictions, which may be due to the projectile breakup processes in these reactions. At higher projectile energies (≈10 MeV/nucleon), Wilczynski et al [9] have well explained the cross-sections for ICF reactions based on partial statistical equilibrium and on the idea of a generalized concept of angular momentum. However, on the basis of the above prescription, ICF reactions could not be explained at lower projectile energies, where the maximum angular momentum values ( max ) are less than the critical angular momentum ( critical ).…”

Investigation of complete and incomplete fusion in20Ne +51V system using recoil range measurement

“…Thus, fusion is restricted by crt above which no CF reaction is likely to occur. According to sumrule model, proposed by Wilczynski et al [18], ICF reaction channels are localized in angular momentum space above crt . At lower energies max is close to crt , thereby precluding any window for ICF reactions.…”

“…Moreover, at relatively higher projectile energies the concept of critical angular momentum distinguishes both the reaction dynamics. As per sharp cut-off approximation, the probability of CF is assumed to be unity for l ≤ l crit and zero in case of l ≥ l crit [7]. Hence, at relatively higher projectile energies and at larger impact parameters, CF moderately gives way to ICF, where fractional mass and charge as well as the linear momentum of projectile are transferred to the target nucleus, due to the prompt emission of α-clusters in the forward cone with almost projectile energy.…”
